Title: Acoustic chamber for the aerosol treatment of exhaust gases
Inventor: MAGILL JOSEPH
IPC: B01J19/10
Filed: 1991-11-25
Abstract: The invention relates to an acoustic chamber (3, 6, 7) for the aerosol treatment of exhaust gases, which are to flow through the chamber and which are exposed therein to an acoustic field.  According to the invention, the chamber has a regular polygonal cross-section and the sound sources (4, 5) transmit sound waves into thechamber under such an angle that the sound is repeatedly reflected from the walls of the chamber before it hits on the other end of the chamber a sound reflector (8, 9). Due to the intensive irradiation, fine dust particles are put into vibration and coagulate to larger grains, which can then be filtered away.

Title: Infra-acoustic/electric fish fence
Inventor: OSTLIE LARS
IPC: A01K63/00
Filed: 1992-06-25
Abstract: An immaterial fish fence is based on a combination of low frequency mechanical vibrations and synchronously modulated electric fields, where fish approaching the fence, will be given at the same time fear reactions and directional information by the mechanical vibrations, and in addition feel pain due to the electric field.  The fish will then turn and swim away. The fence is implemented by means of columns positioned side by side, each comprising a number of low frequency transducers (1) suspended above each other, each column being suspended in a float (4). Each column also has two electrical conductors (2) to which a high voltage can be delivered, and thus synchronized fields of both acoustic and electric type can be generated between and around the columns.

Title: Water isolation system
Inventor: SAGE-PASSANT PETER
IPC: E03B7/10
Filed: 1994-03-30
Abstract: ABSTRACT            A water isolation system comprises a valve (1) in a water flow line (10), with a latched solenoid to open or close the valve. A power source operates the valve with an electrical switch (2) causing pulsed actuation of the solenoid on operation of the switch.  The solenoid is unpowered when the switch is not being operated.  The switch (2) is located at a convenient point within a building to which the water is supplied, which point may be remote  from the water  flow  line,  such as  adjacent  a main entry/exit door to the building.            Use of the system allows the water supply to be completely isolated when the building is to be unoccupied for even the shortest period of time.  It also prevents excessive water loss and water damage when there is a burst pipe by being controlled at a point which is easy to reach and thereby switch off the system quickly.  Finally, it can be easily closed to facilitate maintenance or replacement of any part of the water or heating system within the building.
